LOCK.

Application led April 16,

To all whom t may concern.'

Be it known that l, GUsTAv Bnorrnnnn, a citizen of the United States7residingat Belleville, in the county of Saint Clair and State ofIllinois, have invented certain new and useful Improvements in Locks, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to certain improvements in locks and has relationmore particularly to a device of this general characterV especiallydesigned and adapted for use in connection with automobiles or the like,and

it is an objectof the invention to provide a lock of this generalcharacter having novel and improved means whereby the steering post isheld against rotation.

It is also an object of the invention to provide a lock of this generalcharacter including a shackle coacting with the post of the steeringmechanism and which shackle when in one position holds the post againststeering movement and when in a second position permits unobstructedoperation of the post. y

Another object of the invention is to provide a lock of this generalcharacter including a steering post engaging memberl together withpermutation means coacting with said shackle for controlling the desiredadjustments thereof, together with mechanism whereby the permutationmeans is held against removal or displacement when the shackle is inlocking or holding engagement with the post.

rlhe invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved lockwhereby certain important advantages are attained and the device ren`dered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed. I

In order that my invention may be the better understood, l will nowproceed to describe the same with reference to the accompanyingdrawings, wherein:

Figure l is a fragmentary view partly in top plan and partly in sectionillustrating a lock constructed in accordance with an embodiment of myinvention and in applied position.

taken substantially on the line 2-2 of Figure l. l'

Figure 8' is a fragmentary view taken through the steering tube and postwith the shackle shown in elevation and in a second position. y

Figure 4 is a View partly in section of anism as herein included. f

Figure 5 is a view also partly in elevation and partly in section andparticularly illuspartly in elevation and they permutationl mechtratingthe means for holding the permutation means against displacement, and

Figure 6 is a transverse sectional view taken through the permutationmeans with certain of the parts in elevation. As disclosed in theaccompanying drawings, l denotes the steering gear tubing or columnthrough which is directed-the steering post 2. The portion of the post 2adjacent the lower end ofthe tube or column l is provided with theopposed flattened faces 3 arranged substantially in parallel- .ism andwith which coacts theshackle S. The shackle S has one end portion 4enlarged and adapted to loosely surround the post 2 when the shackle israt the limit of its movement in one direction so .i that no hindrance orobstruction `willbel offered to the requisite rotation of the is desiredto effect a steering opposite-end portion 5 `of the shackle isrestricted transversely and includes the parallel members a whichoverlie the flat faces 3 of the post 2 when the shackle is at the limitof its movement in the opposite direction so Athat said shackle servesto hold the post- 2 against rotation. In practice, it is particularlydesired that ythe shackle S, or more particularly the arms afthereof,coact with the flattened faces 3 of the post 2 after said post has beenrotated to throw or swing the steering wheels to substantially a quarterturn. i

The shackle S is arranged within the tubing or column l and is carriedby an yend portion of an elongated arm G which extends through anopening in the lower portion of the tubing or column l and the outer endof said arm 6 is provided with meansfor controlling the desired movementthereof for the requisite adjustment of the shackle S andV which meansare herein disclosed as of a permutation character.

post 2 when it operation. The

Suitably secured to the dash D is acasbeen removed from within thecasing 8.

The outer face of the casing 9 is provided with the integral closingplate 11 provided with a suitab e opening 12.

Disposed through the opening 12 and eX- tending within theV casing 8 isa spindle 14 having arranged thereon a plurality of nested sleeves 15and said sleeves 15 and spindle 14 are capable of independent rotation.The portionsof the spindle 14 and the nested sleeves 15 within thecasing 8 have secured thereto the discs 16 of the same major diametersand the periphery of each of said discs is provided with a recess ornotch 17 adapted to substantially transversely alineV on` pro ermanipulation oi' the spindle'14 and t e sleeves 15. Ther outer .endportions of the spindle 14 and the sleeves 15 are provided withoperating flanges or knobs 18 so that said spindle and sleeves Vmay beindependently rotated in accordance with thel desired combination torelativelyadjust the discs 16 to bring the notches 17 into desired"registration or alinement.

lThe assembled casings 8 and 9 are pro-V vided"withtheregistermgopenings 19 in a side wall throughwhich the outer end Vportionof the arm6 is directed. Pivotally engaged with the end portion of the `arm 6within the casing 9 is an end portion of an elongated tumblervorswinging arm 2O andv said tumbler orarm 2() is provided with atransversely disposed depending flange or li" o the various discs 16 andof a width to drop within the `registering or alining recesses 17. `Whenthe lip or flange 21 is seated within the alined or registering recesses17, it will be obvious that upon rotation of one or more of' the discs16, the arm 6 will be moved into position to adjust thev shackle S intolocking or holding position or vice versa. Y

I also find it of importance to provide means-whereby the casing 9 islocked or held against removal or displacement from within the casing 8and particularly when the shackle S is in locking or holding position,so that the possibilityT of tampering with the device byl anunauthorized person is substantiall entirely eliminated. As hereindisclose' the spindle 14 inwardly of the discs 16 has looselymountedthereon a bushing or sleeve 22 provided with the oppositelydirected armsQB and pivot-ally end with each of said arms 23 is an endportion of a link 24 having its opposite end portion pivotally engagedwith a bolt 25.

Each of said bolts 25 is slidably supported within an opening 26 inaside wall of 21 of a length to engage the peripheries the casing 9 andwhich opening 26 registers with an opening or recess 27 in the adjacentside wall ofthe casing 8. One of the arms 223 has pivotally engagedtherewith an yend portion of another link 28 having its opposite endportion pivotally engaged with the arm 6 so that when the arm 6 is movedin a direction to adjust the shackle S into locking or holdingengagement with the post 2, the arms will he swung in a direction tomove the bolts 25 outwardly and within the openings 27 so that thecasing 9 is effectively held against displacement until after the arm 6has been moved in the opposite direction toadjustthe shackle S into theinactive or neutral position illustrated in Figure 2 of theaccompanyingl drawings.

When itis desired to move the arm 6 outwardly to cause thearms a of theshackle to coactwith the flattened faces of the post Q, the discs 16 arerotated in a direction toward the tubing or column 1. At the beginningof this operation it is to be understood that the flange or lip 2i isseated Within the aligned orregistering recesses 17. As the discs 16 arerotated and the arm 6 moved outwardly, the recesses 17, Vas the samepass downwardly beyond thevertical center, will free from the angev orlip 21 whereupon said lip or flange will ride upon the unobstructedperipheries or' the discs 16 and at a point in advance of the dependinglug` 20 carried by the upper portion Vof the su plemental'casing 9. Thisdepending lug 2E provides an abutment with which the free end. portionof the tumbler or arm 20 contactsrto hold the arm 6 against movementinwardly of the casings 8 and 9'.

W hen it is desired to retract the arm` 6, the discs 16 are relativelyrotated in accordance with a predetermined combination to cause therecesses 17'to align below the flange or lip 21 of the arm or tumbler 20when thearm 6 is in extended position.

When the recesses 17 are so aligned, the flange or lip 21 will falltherein so that upon requisite rotation of the discs 16, the arm 6 willbe properly retracted.

When the arm 6 is retracted as disclosed in Figures 4 and 5 of thedrawings, it is not necessary that the flange or lip 21 be :free of Atherecesses 17 and which disengagement is prevented bythe depending lug 20.

From the foregoing description, it is thought to be obvious that a lockconstructed in accordance with my invention is particularly well adaptedfor Vuse by reason of the convenience and facility with which it may beassembled and operated, and it will Y also be obvious that my inventionis susceptible of some change and modification without departing fromthe principles and spirit thereof and tor this reason I do not wish tobe understood as limiting myself to the precise arrangement andformation ot the several parts herein shown in carrying out my inventionin practice except as hereinafter claimed.

I claim:
